Phoebus Posted September 5 Share Posted September 5 I received my brand new Tracer9 yesterday (yeeey! :-)). Been riding approx 20 years, but this it my first bike with any electronics aside standard (non-cornering aware) ABS. I set BC to 2 as I see no reason to turn cornering ABS off for road use. Have everything else at 1 as default from the factory. I'm not trying to do any wheelies, burnouts, or similar stuff, but am still wondering about the system's capabilities (and not willing to try it 🤣). I'm not afraid of wheel spinning a little on straight, been there, done that. But does this traction control prevent (low side) fall if I'd be too eager with throttle while trying to accelerate out of the curve (i.e. while leaning)? Again, I'm not trying to do anything stupid, just being curious Thanks Link to comment Share on other sites More sharing options...

The IMU enabled "lean-sensitive" ABS and traction control are technically 'smarter or more advanced', meaning the IMU can detect the bike leaned over in a corner and is supposed to be more refined in how it detects and reacts to wheel spin. Bear in mind that nothing will save you if you lose the front end (slide) in a corner but the advanced systems will intervene if the rear wheel slips or a difference between front and rear wheel speed is detected and cut power if you are accelerating or reduce braking if it detects the ABS engage. To answer your question, it will be more sensitive than the older system but there is no 'guarantee' that you cant still low side if you hit gravel, ice or oil, it cant give you traction where there is none. 2 ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...

Again, I'm not trying to do anything stupid, just being curious Thanks Your post title asks about TC (Traction Control) but in your post you mention BC, which controls how the ABS on the bike behaves, just to be clear they are not the same thing. Traction Control prevents wheel slip while putting down power, by cutting power to the rear wheel. ABS prevents wheel slip from while braking by adjusting hydraulic brake pressure to prevent brake lockup. To answer your question: Yes, TCS (traction control) will try to prevent you from low siding in a corner if you're too heavy on the throttle while leaned over. It's pretty aggressive in setting 2, but you could probably still slip if you suddenly pinned the throttle at apex on a wet surface. No, BC2 (cornering ABS) will not prevent you from low siding in a corner because braking while the bike is leaned over causes it to stand up, which will result in either not making the corner or a high side. BC2 tries to prevent this. If you haven't already, read your user's manual outlining the special features as Yamaha's stability system is broken into 3 categories: TCS, SCS, and LIF, all of these work together to keep rear wheel traction and prevent wheel slip while putting down power. You can customize each of these individually in TCS-MODE M to your liking. 1 Link to comment Share on other sites More sharing options...
PhotoAl Posted September 6 Share Posted September 6 TC is great when cornering. Have no experience with the T9. My first bike with traction control was a 2014 Kawasaki ZX6R 636. Not long after I bought it was going around a moderately tight curve and being a careful sport bike rider I never, no never was exerubent with the right wrist 🙂 Hit a small 9" depression with a bit of dirt gravel in it. My previous bike, CBR600RR, would have steped out a bit hitting that but nothing crazy. The ZX6R had the slightest stutter but the bike was rock solid with only the very slightest movement. Impressive I thought, the bike detected the rear spin and chopped the power instantly. Note that this has nothing to do with front wheel grip but only the real wheel spinning from too much power being applied. While it won't save you from a total bone headed move it will pull you back from the edge. Spinning the rear wheel while cornering can lead to a low side but can also lead to a high side. High sides make great photos and videos and broken riders. I've always considered the safety systems like ABS and TC to be safety nets. Hopefully they will never be needed but on unfamilar roads and particularly in wet conditions it is easy to misjudge traction. 1 Link to comment Share on other sites More sharing options...
Phoebus Posted September 6 Author Share Posted September 6 Thanks all. Yeah I only mentioned BC to "remove it out of equation" because it was natural to me to keep the cornering thing on (despite I try never to break mid-corner and even when I do emergency braking, I naturally "gentle squeeze" it as opposed to slam on it like they taught my wife when she passed her license 4 years ago [ABS is mandatory over 125cc for new bikes in EU and they now teach "just slam it"]. I just can't slam them.). The manual indeed clearly breaks down TSC, SCS and LIF but doesn't go into details what "least intrusive" (1) or "most intrusive" mean...due to obvious reasons, I suppose - so that's why I asked. I'll keep them in 1 or maybe play around with 2. As I said, I'm not trying to do binary throttle or anything like that, was just curious, and will treat them like @PhotoAl said - a safety net for unforeseen slippery patch of road. 1 Link to comment Share on other sites More sharing options...
Fleng Posted September 6 Share Posted September 6 In my manual mode I keep everything as in the “street” mode, so all very safe. Never got into situations that it needed to take over. At least I never noticed it… Only difference is the shock settings, I set it not the harder setting for use at good roads as we have here. When on more bumpy roads, I just set it to street for the softer setting. All I need. Link to comment Share on other sites More sharing options...
bwringer Posted September 6 Share Posted September 6 My 2015 FJ-09 has the older TC system that's just on or off, but I can tell you that it's like magic. One of the first things I did when I got the bike was to intentionally give it too much throttle in some corners with gravel and dirt; not so much power I couldn't recover on my own, but enough to see what the system did. It really does intervene pretty seamlessly. You notice the power isn't what your wrist called for, and you might notice the TC light blinking at you. Obviously it can't manufacture traction where there is none, but it will make the most of what you have and at least keep the throttle from getting you into trouble. On a very hard run up a letter road in Missouri, I noticed the blinking light launching out of several corners, and decided maybe I should back off a touch. It had been very very dry of late, and I think the road had a layer of dust that hadn't had a chance to wash off, and was reducing traction a bit. I didn't really feel a thing, just noticed the light. Go ahead and play with it a little on a road with a loose surface; make sure you have enough room to recover, and that there's at least some traction. I think it's important to teach yourself what these systems can and can't do and what they feel like when activated. Same goes for ABS; one of the biggest issues with ABS is that people feel the "judder" and let go. 2 Red 2015 FJ-09, among other things.
